TO ALL WHOM IT MAY CONOERN:

Be it known that I, JAMES WIXTED, of :Port Carbon, county of Schuylkill,State of Pennsylvania, have invented animprovement in Railroad Frogs;and I do hereby declare the following to be a. full, clear, and exactdescription ofthe same.

My invention consists in securing the steel points of frogs to thebase-plates ol the same in the peculiar K manner fully describedhereafter, s o that thepoint may be Jfirmly held in its place .withoutdetracting from-the solidity and strength of the said plates. Y

In order to enable others skilled in the art to make and apply myinvention, I will now proceed to describe the `mode of carrying the sameinto eiect` reference being had to the accompanying drawing, vwhichforms a part of this specification, and in whichr Figure 1 is a planview of my improved frog.'-

i Figure 2, a vertical section on the line 1 2, g. 1. 1 Figure 3, atransverse section on the line 3-4, g.' 1, and Figure 4, a'transversesection on the line 5-6, tig. 1.

Similar letters refer to similar parts throughoutA the several views. Asregards general form, my improved frog is similar' to those of the'usual construction, and consists cf the cast-iron plate A secured to thetrack by bolts or spikespassing through lugs a, as usual, ribs or railsI and b projectingvfrom the uppersur'ace, and forming a part of thisplate, and theseribs being faced with steel in the ordinary manner.There is also between the ribs b and Z1 the usual angular projectio'ne,with a steel facing, f, forming a continuation of the steel point al'.

It is the peculiar manner of securing this steelpoint to which myinvention especially relates.. Ordinary steel points are made of adove-tailed forml atthe lower edge, and are adapted to a dove-tailedrecess formed in the plate A,ia recess which tends to weaken theplate-at a point where the greatest strength is required. On referringto fig. 2 it will be seen that the plate A has no recess for receivingthe point, the plate being simply k 'thicker at its 'narrow than at itsbroad end, so that uniformity of strength may be attained. The steelpoint d is placed on the thinnest portion'of the plate, its extremepoint extending to the edge of the thickest portion, the rear of thewidest end of the point being overlapped by the end of the steel facingfof the angular projection e, 4as seen in fig.

Itis most'important in all railroad frogs that the point should be sosecured as to eifectu'allly resist all lateral strains,` a securityd-ependent in ,ordinary frogs onthe recess `in the plate A, which recesscannot be' made withoutrendering the said plate defective as regardsstrength. To obviate this I'secure to the plate A wrought-iron or steelstrips m m, oneon each side of the point d, by bolts, one strip fittingaccurately between ea'chrib b and I1 and the point, so that the lateralstrains imparted to the latter will be resisted by these strong ribsorrrails instead oi' being communicated to aplatc, A, so weakened by arecess as to superinduceits fracture.

I claim as my invention, and desire to secure by Iietters`Patent Thesteel point d, confined to the plate A of a frog, and between the railsor ribs b and b' of the same, by p the wrought-iron or steel strips m m,all substantially as and for the purpose herein set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnessesg JAMES WIXTED.
